FETUB and metabolic dysfunction-associated steatotic liver disease: On the other hand, taking the studies which compared fetuin-B concentrations between patients with NAFLD and the controls, it was found that fetuin-B concentrations were higher in patients with NAFLD than in the controls, with low effect (SMD = 0.18, 95% CI: 0.02 to 0.33, p = 0.023), and moderate heterogeneity (I2 = 62.3%).
